What is the recommended depth for chest compressions on an infant?

The recommended depth for chest compressions on an infant is approximately 4 cm, which is about one-third of the depth of the chest. This depth ensures that the compressions are effective in generating sufficient pressure to circulate blood, which is vital for maintaining perfusion to critical organs during cardiopulmonary resuscitation (CPR).

In infants, the technique and depth of chest compressions are crucial due to their smaller size and more vulnerable physiology. Compressions must be deep enough to create adequate intra-thoracic pressure without causing injury to the delicate structures within the chest.

Using a depth of one-third of the chest allows for both effectiveness and safety in performing CPR on infants, addressing the unique anatomical considerations present in this age group.
